To all "to hem it may concern I Be it'known that" I, EDGAR- J Broom-r, acitizen of the United" States; r'e sidin at Tiflh in the countyof-Senecaand b tate of Ohio, have invented certain newandnse fulImprovements in Oil-Cups; of which the following is a specification.

This invention relates to oil"- cups and has for itsfiobject' an oil cupadapted te dep'endably' teed very minute uantities: of oil at arelatively slow rate: he 'cup is ar ranged to be attached to a movingmember, which causes the 'oil in the reservoir" to splash up on the endofthe stand pipe, whence it is-all'ow'ed'tofeedlinniinute quantities outoft'hje' up; into thef bearing,

An improved featureof this cup is that provision is made to verysecurely anchor the" oil col'lectingupon' the end of the stand pipe sothat it will stay there and afl'ord aunitorm and dependable feed. Thiswill more plainly appear in the specification following.

In the drawings,

Figure 1 is aside elevation of the improved cup.

Fig. 2 is a vertical section.

Fig. 3 is a plan view of the barrel of the cup. 7 V

Fig. 1' is an inverted plan view of the cap.

Fig. 5 is an enlarged fragmentary vertical section showing thecorrelation between the collector cone. of the cap and the end of thestand pipe. M

Fig. 6 is a similar view showing a modified form.

a designates the barrel of the cup havingits lower end formed into ahexagonal wrench-hold Z) and an integral extension in the form of apipe-threaded nipple c. Interiorly and in alinement with this nipple isa stand pipe 03 whose'upper end is drilled to form a conical basin 6. Atthe bottom of this conical basin is a very small opening approximating1/70th of an inch and which may properly be called a capillary opening,designated f.

The cap is formed in the regularway except that it is provided with anenlarged central portion forming a cone g, which is an oil collector forthe oil that is splashed up on the interior of the cap by the movementof the oil cup. These oil cups are primarily intended to be attached toautomobiles or other moving parts. The consequence is .the oilis swashedaround the cup and dashed against the interior of the cap. Thiscollector cone causes theoil to flow down into the basin e, where itfeeds through the capillary opening. f into the interior of the standpipe and thence into the bearing;

ery important featu're'of this cup is that it employs the principle ofair exolilsion-in restraining the flow through the capillary orifice f.This is accomplished by" usingthe' leather or other soft washer h in-aseat inthe cap'between thecone andthe cap' flange. Tliisfengag es thetop of the barrel when the cap is screwed down and aflord'sasubstantially air-tight fit.- -Inas"- muclras the restofthe cup'isasingle integralpiece; no aircan enter thejc'u-p unless it"be throughthe capillary opening. Ob

asthe resistance of the liquid constantly air to pass up through thiscapillary opening. The walls of the capillary opening viously this ispractically an impossibility I and the walls of the basin and cone areso close together that the capillary adhesion of bearing.

With the cup having no washer h, ordinarily no air tight fit can besecured here. Hence the air pressure is always behind the oil collectingon the cone and very much facilitates the oil running through thecapillary opening. It is a well known fact that an air-tight jointcannot be secured between the ordinary metal to metal contact unlessthere be a ground joint.

is out of the question in producing oil cups.

Of course, this Another improved feature is that the apex of the coneruns down below the rim of the basin. This serves to very securelyanchor the oil in the basin from being slopped off the standpipe by thevibration of the car or other machinery parts. In Fig. 6 the apex of thecone is eratered. This provides an additional anchorage for the oilpillar formed between the end of the cone and the top of the stand-pipe.It is very desirable to have the oil which does collect at this pointvery securely anchored for obviously if only part of the time it ispresent, no regularity of flow can be achieved. In fact, the fasteranautomobile runsand the the violent movement shaking the oil off from thetop of the stand-pipe. This anchoring arrangement insures a propersupply of oil for the parts of an automobile even when running at a veryhigh speed.

What I claim is 1. An oil cup, having in combination, a barrel, astand-pipe therein provided with a basin in its top havinga'capillaryopening between the bottom of the basin and the interior of thestand-pipe, a cap for the barrel, and a collector member supported overthe stand-pipe and havin its lower end dipping into the basin below t erim thereof for the purpose of anchoring oil collecting between thebasin and the collector from being shaken off vfrom the top of-the pipe;

2. An oil cup, having in combination, a

barrel, a stand-pipe therein provided with the pipe, a cone suspendedover the top of the stand-pipe and having its apex dipping into thebasinbelow the rlm thereof to form an anchorage for oil collecting at thispoint,

-and aclosure for said barrel. greater the need of lubricant, the morewould the flow be cut down by reason of 3. An oil cup, having incombination, a barrel, a stand-pipe therein provided with a depressionin its top formin a basin having a capillary opening leading there-'from into the interior of the stand-pipe,

and a cap provided with an enlarged central 7 portion forming acollecting cone whose apex dips into the interior of the basin and isbelow the rim thereof.

4. An oil cup, having in combination, a barrel, a stand-pipe thereinprovided with a depression in its top forming a basin having a capillaryopening leading therefrom into the interior of the stand-pipe,acollecting cone suspended above "the stand-pipe. and having its apexboth cratered and extending closure for the top'of mammal; In testimonywhereof I afiix my signature.
